The highest path of Jnana is no thinker left to think at all.
Nobody is home.
There is a total blank.
There is no one around to do any thinking or preparing anything or trying to solve a problem or trying to do anything.
At that stage you're totally free.
When you devote yourself to the Self, when you become a devotee of the Self, this means that you surrender all of your fears, your frustrations, your goals, your needs, your lacks, your limitations, everything is totally surrendered to the Self.
This is devotion.
